I can't comment on the 2011 caps, but I do have a pair of the 2006 capsules with the compact bodies. I have only had the opportunity to record four sets with them so far (moe. and Mike Gordon on the first and third nights of the recent Jam in the Dam), but my first impressions are quite good. Well balanced and detailed, with (perhaps) a touch of bass roll-off compared to other DPA omnis. That opinion is still kind of half-formed at this point, though, because I was not in my usual recording environment (different type of music, a bit further back than I'd prefer with omnis, and a generally more noisy crowd). I also haven't subjected them to an important test: the Dynaudios. Not to mention, those were my first recordings with a new pre...I'll have some chances over the next month to record in more typical situations, so that should help me with the personal evaluation!
Let me know if you are interested, and I can get a couple of samples together.
Mine are, DPA "on the 'cheap'" is still DPA. Best part is if you later want to upgrade, you can just buy new caps, not a whole new mic system. Also, with the small shotgun that is apparently sort of close to a hyper, it finally gives them a fullsize more directional mic in their line.
Initial reports on the build quality here have been that they are as good or even better than the Schoeps Colette series, which is pretty damn high.
I think this new DPA system is very compelling and intriguing, overall. It's a more logical line in terms of flexibility than what they had.
These two factors were, basically, what led me to buy these mics. I had wanted the wide card compacts (4026/7/8) for a good while, but never had the cash to spare. When the modular system and the compact bodies became available, I figured I could take the interim step of buying the less expensive omni pair and then get a pair of the 4015 caps (and the 4006s and the 4011s) when funds were there. I was additionally attracted to the flexibility, not only of the interchangeable caps, but also in terms of cabling...
